Specification of Letters Patent.

Patented Nov. 26, 1916.,

Application filed January 11, 1916. Serial No. 71,562.

To all whom t may concern:

Be it known that I, HIRAM C. FONDE, a citizen of the United States,residing at Birmingham, in the county 0f Jefferson and State of Alabama,have invented a new and useful Heater, of which the following is aspecification.

The device forming the subject matter of this application is a woodburning heater adapted to be assembled with a bath tub, for the doublepurpose of heating water which is to be discharged into the bath tub andheating the room wherein the bath tube is located.

The present invention aims to provide, in a device of the typedescribed, a novel form of coil which will present a maximum amount ofarea to the fuel, thereby economizing the fuel.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawing, the invention is shown in a single verticalsectional figure.

In carrying out the present invention there is provided a heaterembodying an ash pit 1 supported on legs 2 and provided with an ash door3, the ash pit l containing an ash pan 1. Supported on the ash pit 1 isa base 5 upholding a drum 6 preferably ofcircular contour, the drum 6being provided adjacent its bottom with a lighting door 7 Supported bythe drum 6 is a top 8 having an opening 9 closed by a removable cap 21.rlhe grate is indicated by the reference character 20. The top 8 carriesa collar 10 cooperating with a flue 11.

Disposed within the drum 6 is a spiral coil of pipe 12, the lower end ofwhich opens into an inlet 14C projecting outwardly through the drum nearto the bottom of the drum.

rIhe upper end of the coil 12 communicates with a vertical, U-shapedextension l5 lying within the flue 11 and embodying a depending arm 16extended downwardly within the contour of the coil 12, to a pointadjacent the bottom of the coil. The arm 16 communicates with a lateralpipe 17 extended outwardly through the drum 6 and entering the bath tub.1.8, the pipe 17 being terminally equipped with a cock 19.

In practical operation, combustible material, ordinary wood, isintroduced into the heater within the contour of the coil 12.V

lVhen this combustible material is lighted, water passing through thecoil will be heated rapidly and, at the same time, the apartment whereinthe bath tub 18 is located, will be heated also. r1`he presentinvention, therefore, provides means whereby, through theinstrumentality of a single heater, water delivered to a bath tub, andthe air in the apartment wherein the bath tub is located may be warmed.Owing to the fact that the coil 12 communicates with the U-shaped pipe15, the latter, lying within the flue l1, will increase the amount ofheating surfaces provided and, at the same time, render it possible, tolocate both the inlet and the outlet end of the coil adjacent the bottomof the heater.

Having thus described the invention, what is claimed is In a device ofthe class described, a heater comprising a drum; a coil within the drumand comprising superposed convolutions, the lower convolution of thecoil opening laterally through the heater adjacent the bottuom of theheater; a flue assembled with the heater; and a U-shaped pipe connectedwith the upper convolution of the coil and projecting upwardly into theflue, the U-shaped pipe embodying a depending arm extended downwardlywithin the contour of the coil to a point adjacent the bottom of theheater, and prolonged outwardly to a point beyond the heater.

1n testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
